VIN & USDM Swap Verification Recommended: Swapping a JDM EJ20 into a USDM chassis may require swapping over intake manifolds, engine wiring harnesses, crank/cam sprockets, or sensors. Call us at 403.471.7150 or include your VIN in the order notes so we can confirm exact variation matching for your chassis!
JDM engines are sold as complete assemblies as shown in photos, including core intake and exhaust components. However, because Japanese domestic plugs, emissions, and sensor layouts differ from North American models, plan to swap your original sensors and harness for USDM compatibility:
| Included (Attached Core Accessories) | Transfer / Swap From Original Engine |
| ✅ Engine Block & Cylinder Head Assembly | ❌ USDM Engine Wiring Harness & ECU |
| ✅ Intake Manifold & Throttle Body Assembly | ❌ Sensors (USDM Crank/Cam Sensors, Knock Sensor) |
| ✅ Fuel Rail & Injectors | ❌ USDM Emissions & Vacuum Lines |
| ✅ Exhaust Manifold & Turbocharger (Turbo models) | ❌ Alternator, AC Compressor & Power Steering Pump (If different) |
| ✅ Timing Covers, Valve Covers & Oil Pan | ❌ Starter Motor |
